    Effect of new generation fertilizer application on cold storage of ‘Owari Satsuma’ mandarin
    (International Society for Horticultural Science, 2024) Karasahin, Z.; Unlu, M.; Kafa, G.; Polatoz, S.; Uysal, O.; Karatas, N.; Arslan, R.
    This study, carried out at the Directorate of Alata Horticultural Research Institute, compared the effect of classical fertilizer and new generation fertilizer applications on cold storage of ‘Owari Satsuma’ mandarin. ‘Owari Satsuma’ mandarin fruits, where classical fertilizers and new generation fertilizers were applied, were harvested at optimum maturity (when 75% of the fruit peel turns yellow-orange), were stored at 4(±0.5)°C and 85-90% relative humidity 75 days. Analysis was done every 15 days during storage. Physical and chemical changes (weight losses, total soluble solids, pH, titratable acidity, fruit skin color (L*, C* and hue value), content of juice and fungal disorders were determined during storage. According to the findings, in storage mandarins, the average weight loss was determined as 8.42% in 2017 and 5.47% in 2018 in the control application, 8.18% in 2017 and 5.93% in 2018 in the new generation fertilizer application. There was no significant difference between the effects of classical fertilizer and new generation fertilizer applications on the preservation of ‘Owari Satsuma’ mandarin in the cold. © 2024 International Society for Horticultural Science.

    Preliminary results on morpho-pomological traits and pollinizer characterization of some caprifig genotypes grown in Eastern Mediterranean region of Turkey
    (International Society for Horticultural Science, 2017) Caliskan, O.; Bayazit, S.; Ilgin, M.; Karatas, N.; Kocataş, H.
    This study was carried out on 77 caprifig (Ficus carica var. caprificus) genotypes grown in Eastern Mediterranean region of Turkey. Caprifig fruits were harvested to determine the morpho-pomological and pollinizer characteristics in 2014. Significant phenotypic diversity was detected among caprifig genotypes based on the fruit quality traits. Fruit weight ranged between 8.96 and 55.14 g, fruit width between 30.15 and 60.43 mm, fruit length between 27.70 and 67.68 mm, ostiole width between 0.00 and 5.80 mm. The number of Blastophaga wasps per fruit resulted to be between 167.7 and 1080.8 and the number of male flowers between 6.0 and 256.4. Hatay05, Hatay08, Mersin04, Hatay16, Hatay28, Hatay06, Mersin02 and Mersin11 genotypes scored the highest overall quality according to the weighted ranked method. Our study demonstrated that there was great morpho-pomological and pollinizer variability among the caprifigs grown in eastern Mediterranean region of Turkey, making them a valuable genetic source for incorporation into potential breeding programs and also caprification application.
